I've noticed there seem to be a lot more remote Rails jobs than anything else (other than Javascript). I know some Ruby and am also thinking about Rails, despite my preference for Python- there just so few Python or Django remote jobs unfortunately I need to broaden my horizons.
The problem is that the maturity of the Rails market means that most Rails positions require X number of years experience - I can certainly pick up Rails but those years of experience have to come from somewhere.
EDIT: not entirely true, as there are a lot of PHP jobs. However these include bottom-feeder Wordpress gigs and generally pay much lower salaries than other languages, right or wrong.
